*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

The Arkansas River, one of the major rivers in the United States, flows through Colorado, Kansas, Oklahoma, and Arkansas, offering a diverse range of climates along its course. Water temperatures in the Arkansas River vary depending on the region and season. In Colorado’s higher altitudes, where the river originates, temperatures remain cooler year-round, often below 60°F (15°C), even in summer. Farther downstream, in warmer climates like Oklahoma and Arkansas, summer water temperatures can reach 75°F to 85°F (24°C to 29°C), making those sections more inviting for water activities.
Swimming opportunities in the Arkansas River exist but are largely dependent on the location and water conditions. In its upper reaches, the river is better known for whitewater rafting and kayaking due to its fast-moving currents and rapids. In calmer, downstream areas, particularly in Arkansas, the river provides more accessible spots for swimming and wading, often near parks or recreational facilities. However, caution is advised, as the river's flow can be unpredictable, and sections may have strong currents or debris.
For those seeking to enjoy the Arkansas River, it’s best to research specific areas and consider local advisories. Many people prefer engaging in other water-based activities like fishing or boating, which are popular along the river’s extensive course. Regardless of how you choose to experience it, the Arkansas River remains a vital and versatile resource for recreation and nature enthusiasts.
